Las infecciones fúngicas causadas por Aspergillus sp. y Candida sp. son causa importante de morbilidad y mortalidad en pacientes gravemente inmunodeficientes, especialmente en aquellos con neutropenia o receptores de trasplante de médula ósea o de órganos sólidos. Informamos sobre una hialohifomicosis cutánea en una mujer de 24 años de edad con leucemia linfoblástica.
Invasive fungal infections most frequently caused by Aspergillus sp. and Candida sp. are significant causes of morbidity and mortality in severely immunocompromised patients, especially those who are neutropenic or who have undergone bone marrow or solid-organ transplant. We report a case of cutaneous hyalohyphomycosis in a 24-year-old female with acute lymphoblastic leukemia.

Histiocytic sarcoma (HS) is a rare malignant neoplasm of the lymphohematopoietic system, that occurs in lymph nodes, skin and at extranodal sites, particularly the gastrointestinal tract. Although it shows characteristics histoiogical and immunohistochemical features, it may be misdiagnosed. We report a 67 year-old female patient presenting with colicky abdominal pain and vomiting. A CT sean of the abdomen revealed a tumor in the ileum, that was surgically removed. On pathology, the neoplastic cells displayed large abundant eosinophilic cytoplasm, with bizarre-shaped nuclei, that expressed CD 45, CD 68 and lisozyme. The diagnosis of HS requires the use of a panel of immunohistochemical markers and may be supported by ultrastructural findings .
